Application filed une 18, 1914. Serial No. 845,964.

To all whom it may concern:

Be it known that T, SARAH E. AVERY, citizen of the United States, residing at Columbia, in the county of Richland and State of South Carolina, have invented certain new and useful Improvements in Folding Sewing-Machines, of which the following 1s. a specification.

This invention relates to an improvement in folding sewing machines. i

The primary object of the invention 1s to provide a sewing machine which may be folded to occupy a comparatively small space and in which the bed-plate and the arm which supports the needle actuating mechanism may be housed within a cabinet and the driving mechanism folded on the cabinet and maintained in its folded position by the supporting table for the bedlate. p A further object of the invention is to provide a construction in which the various parts may be readily folded and which when unfolded for use will operate as effectually as the usual sewing machine construction. v

A still further object of the invention is to provide a mechanism of this character in which all of the mechanical parts will be eifectually housed, whereby the device may be conveniently transported.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a front elevation of the machine set up for use; Fig. 2 is a front elevation partly in section showing the device folded; Fig. 3 is a section on the line 3-3 of Fig. 2; Fig. 4 is a section on the line 4-4 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings, 10 designates a cabinet which may be of any suitable design, but which preferably consists of the base portion 11 which supports a plurality of drawers 12. The cabinet is formed with a compartment 13, a lid 14 being hingedly connected to the cabinet and forming a closure for this compartment. The ledge with which the cover 14 contacts is formed with an extension 15 atl one side of the cabinet and to this extension is hingedly connected a table 16. This table is supported by a plurality of braces 17, there being a brace 17 hmgedly mounted adjacent each edge of the cabinet below the extension 15. These braces 17 are disposed to fold on the cabinet and when the machine is set up for use they effectually support the table 16. The table 16 is provided with an opening 17 which receives the flange 18 of the bed-plate 19 on which the arm 20 which houses the needle actuating mechanism is mounted. This needle actuating mechanism may be of any suitable constructiom The bed-plate 19 is hingedly mounted at one side of the top of the cabinet, and the plate may thus be folded to dispose the arm 20 within the cabinet, the edge 22 of the plate resting upon the iange 23. Tt will thus be seen that the needle actuating mechanism may be folded within the vcabinet and the lid 14 closed.

A sheave 24 is mounted upon the side 25 of the cabinet, a belt 26 passing over said sheave and the sheave 27 of the needle actuating mechanism which is supported by the arm 20 mounted on the bed-plate. The crank wheel 28 is connected with the sheave 24 and a connecting rod 29 is connected to the crank 30 of said wheel. A plurality of brackets 31 and 32 are mounted in spaced relation on the wall 25 of the cabinet adjacent its base. These brackets are provided with spaced ears 33. A treadle 34 is hingedly supported by the bracket 32, said treadle being formed with an extension 35 which is disposed between the ears 33 of the bracket 32, a pin 36 passing through said ears and said eXtension. An arm 37 is pivotally supported between the ears 33 of the bracket 31, said arm being formed with an extension 38 disposed at right angles to its body portion and provided at the point where it is bent with a foot 39.

The treadle is formed with a trunnion 40 mounted upon the extension 38 of the arm The rod 29 is 17 are then folded beneath the extension 1.5 and the table 16 is` lowered. The treadle 1s swung upon its pivotal support and the same, together with the arm 37 andlts extension 38, is brought in contactwlth the wall 25 of the cabinet.

A plurality of hooks 44 are secured .to the wall 25 of the casing, the" terminals of said hooks being inserted within eyes 45 arranged on the under face of the table 16, thereby maintaining the table in spaced parallel .relation to the wall 25 and housing the driving mechanism. It will, therefore, be noted that the entire mechanism of the machine is thus eifectually housed and occupies a comparatively small space. It will also be seen that the entire structure is such as may be easlly and economically manufactured, and that the various parts may be'readily assembled.

What I cla-im is:

1. A folding sewing machine comprising a cabinet provided with a compartment, a table hingedly supported adjacent one edge of said compartment, a base plate hingedly supported by said edge, a needle o eratmg mechanism arranged on said basep ate, the base plate being movable to one position seated upon the table to support the needle operating mechanism in operatlve posltlon and to another position to dispose the needle operating mechanism within the compartment, a driving mechanism having an operative connection with the needle operating mechanism, said driving -mechanism being hingedly supported on the cabinet, said table when folded being disposed parallel with the side wall of the cabinet, and the driving mechanism being. housed between the table and the cabinet.

2. A folding sewing machine comprising a cabinet, said cabinet being formed with an extension, a table hingedly mounted on said extension and disposed to [assume a position parallel with the adjacent side wall of the cabinet, a base-plate hingedly supported on the cabinet and movable to operative position to rest upon the table, a needle operatingl mechanism mountedon said baseplate, said cabinet being provided with a compartment disposed to receive the baseplate and needle operatingmechanism, and

' i a driving mechanism forthe-needle operating mechanism hingedlyz mounted onv the lsa cabinet, said table, when folded, being disposed parallel with the adjacent wallof the cabinet, the driving mechanism being disposed between the table'and the cabinet, and Vmeans for maintaining the table in spaced relation with respect tothe cabinet.

3. A sewing machine comprising a cabinet, a table hingedly supported by the cabinet, means for supportin said table in alinement with the top o the cabinet, a base-plate supported by the cabinet, a needle operating mechanism arranged on said'base-A plate, the base plate being movable to one position seated upon the table to support the needle operating mechanism in operative position and to another position to dispose the needle' operating mechanism within the cabinet, a sheave rotatably supported by the cabinet, a crank disk secured to said sheave2 a lever having an operative connection with said crank disk, a treadle hingedly mounted on the cabinet and disposed to actuate said lever to rotate the crank disk, and means for maintaining the table in spaced parallel relation with the adjacent side of the cabinet, the 'driving mechanism being disposed between said table and cabinet.
